TO THE ISSUE OF MODERNIZATION OF PASSENGER CAR BODIES

Passenger cars owned by JSC "Ukrzaliznytsia" have practically exhausted their resource. Improving the efficiency of railways requires use new innovative technical solutions. The article analyzes condition bodies passenger that worked out A total 540 wagons different years construction were inspected. In course analysis, results inspections metal structures divided into five conditional groups depending on service life. At same time, nominal values thicknesses structural elements car and actual compared. authors determined intensity increase in wear various body. It has been established lower trim, roof slope part side wall greatest wear. is proposed to aluminum alloys for modernization bodies. advantage such a solution an corrosion resistance This significantly increases durability reduces tare weight car. reduction allows reduce specific train movement, fuel electricity costs traction, operating railway transport energy consumption. To using basic provisions locomotive traction theory, calculations made determine consumption movement according profile conditions real section regional branch Southern Railway diesel electric with base variant reduced weight) composition train. calculations, it was considered trains, TEP70 series used AC ChS4 series. annual savings trains when about 1 million UAH. Keywords: car, body, resource, wear, modernization, economic effect.
